I want to have a QWidget with Qt::Popup window flag. But it needs to be non-modal. Even if I set modality to Qt::NonModal, after setting the windows flags, the popup always blocks interaction with the parent.
Is this a bug? A feature? What's a workaround for this?
I'm on Windows.

Widget::Widget(QWidget *parent) :
m_Button = new QPushButton(this);
sample = new QWidget;
sample->setAttribute( Qt::WA_QuitOnClose, false );
@Vinod-Kuntoji it really has to be a Popup, not a FramelessWindow. A Popup doesn't take space in a layout, it is drawn on top other widgets instead.
If you try your code with Qt::Popup you might have the same problem as OP (can't set a Popup to be non-modal)

@cidadao it looks like you want a green ball that is red...
From Qt documentation about Qt::Popup window type enum:
"Indicates that the widget is a pop-up top-level window, i.e. that it is modal, but has a window system frame appropriate for pop-up menus."
so modal it'll be...
@Pablo-J-Rogina got it! Modal forever :)
Still wondering if this OS-specific or just a design choice on Qt's implemantation though.
Finally, the exact answer I was looking for:
Qt::FramelessWindowHint | Qt::Tool
Instead of using Qt::Popup.
